Salt And Vinegar

Salt and vinegar refers to a popular flavor combination that brings together the savory taste of salt and the tangy, sour notes of vinegar. Salt, or sodium chloride, is a mineral typically obtained from salt mines or by evaporating seawater. Vinegar is a liquid made through the fermentation of ethanol, often derived from grains, fruits, or sugar, which produces acetic acid.

Manufacturers add salt and vinegar to foods primarily to create a distinct savory and tangy flavor profile. Salt also acts as a flavor enhancer and preservative, while vinegar contributes to sourness, acts as a preservative, and can regulate acidity. This flavor combination is commonly found in snack foods like potato chips, as well as in pickles, dressings, and sauces.

Both salt (sodium chloride) and vinegar (acetic acid) are Generally Recognized As Safe (GRAS) by the FDA. High intake of sodium, a component of salt, is associated with increased blood pressure, and the FDA recommends a Daily Value of 2,300 mg for sodium. JECFA has evaluated both sodium chloride and acetic acid, and related compounds. While salt and vinegar themselves are not controversial, public health guidance emphasizes moderation of sodium intake.
